Organic light-emitting diodes are seen as the basis for a new generation of lamps: Large-area lamps that can be randomly shaped and fl exibly integrated into interior design. But the "illuminated glass" is still very expensive. ...

In a new study, EMPA researchers have investigated the ecobalances of various household light sources. In doing so not only did they take into account energy consumption, but also the manufacture and disposal processes. They ...

When consumers visit garden centers in spring they will most likely buy flowering ornamental plants that are ready for their home gardens. Studies have shown that consumers favor plants that are already in flower rather than ...

This is a cautionary tale about a few porch lights. Once upon a time, porch lights had incandescent bulbs. Eventually, many residents subbed them out with those swirly compact fluorescent bulbs, which use a quarter of the ...

(AP) -- Light-emitting diodes, or LEDs, are starting to become cost-effective alternatives to standard light bulbs and fluorescent tubes. That opens up some interesting possibilities, such as the combination LED light and ...

University of Pittsburgh researchers have conducted the first cradle-to-grave assessment of light-emitting diode (LED) streetlights and determined that the increasingly popular lamps strike the best balance between brightness, ...

New, particularly high-performance light-emitting diodes (LEDs) from Osram make it possible to build mini projectors. These LEDs produce enough light to project images measuring over one meter in diagonal on a wall. The small, ...

(PhysOrg.com) -- By applying the NetFlix model of movie swapping to batteries, a team of researchers and students from MIT and Harvard is hoping to provide electricity to thousands of homes in Tanzania. Their start-up company, ...
